Exist.
Why have I been able to see differences related to tuning and the stage if I give it burn in?
I notice the sound more mature and the soundstage looser and I would say expansive.
I had understood that since they are balanced armor there should be no changes with the burn in.
I clarify. I do NOT burn in my ears. I test the iems as it arrives and then I run it without listening for x hours.
Why?
I notice this with new sets too,
I put it down to brain burn-in and my ears/ hearing acclimating to the tuning of the new iem.
Well this burn in topic is nation divider since the first inception hah.
Anyhow I do believe in it and experienced it myself.
Some people are simply dead on refusing that such thing might exist because of blah blah insert whatever here. The differences are rarely huge, it’s more like maturing the sound than changing it all together.
But some people also cannot tell any difference in sound between the dacs while I can here ll of mine sounding different and it’s really obvious to me.
Sure some may argue that it’s brain burn in, but when You do it like You have described.
Initial listen and then put away for “x” amount of hours on the burn in rig. Then where is that argument then?
I’m a burn in believer. It happened to my Hype4, it Happened to my ISN H60 which are my first balanced armature iems.
